Blomqvist went on to win the Swedish Rally again in 1972 (Saab 96 V4), 1973 (Saab 96 V4), which marked his first WRC event and win, 1977 (Saab 99 EMS) and 1979 (Saab 99 Turbo).[1] Outside the WRC, he won the 1973 Cyprus Rally, the 1976 Boucles de Spa and the Swedish Rally Championship several times. His long-time association with Saab ended when the Saab Sport department hung up their spurs in 1981. Driving a Talbot Sunbeam Lotus in 1981, Blomqvist finished eighth in the 1000 Lakes and third at the RAC.[1]

During the first two Group A years, Blomqvist continued with Ford and drove a Ford Sierra RS Cosworth, finishing on the podium three times.[1] He also drove for Volkswagen Motorsport and finished third in a Golf Mk 2 16V on the 1989 Safari Rally.The 1990 WRC season was the series' first without Blomqvist in action. In 1991 and 1992, he drove a Nissan Sunny GTI-R for Nissan Motorsports Europe, Nissan's factory team. At the 1992 Swedish Rally, Blomqvist took third place, which would remain his last podium spot in the WRC.[1]

Later in the 1990s, he used his experience of two-wheel drive cars and helped Škoda Motorsport to develop the Škoda Felicia Kit Car. During a guest appearance at the 1996 RAC Rally, when the event was not on the WRC schedule, the 50-year-old veteran finished third overall with the car.[1] That same year, he finished seventh in the Safari Rally in a Ford Escort RS Cosworth. This would remain his last points-finish in the World Rally Championship.[1]

In September 2008, Blomqvist took part in the Colin McRae Forest Stages Rally, a round of the Scottish Rally Championship centred in Perth in Scotland. He was one of a number of ex-world champions to take part in the event in memory of McRae, who died in 2007. He was co-driven by Goñi in a Ford Escort RS1600.
